I recently discovered that the 1992 O-Pee-Chee set included two Braves players left off its American counterpart.
#392 Mark Grant
#405 Nick Esasky
Why the Canadian confectionery company decided to include these two players is a mystery. Granted, both were veterans who had had moderate amounts of success, but each player missed the 1991 season due to injuries. In fact, Esasky would never play in the majors again, with the 1990 season being his final MLB season.
